R. I., assgnors to The Progressive Ring Company, Providence, R. I., a corporation of Rhode n Island 10 Claims.

Our present invention relates to the art of jewelry manufacture, and has particular reference to the manufacture of ornamental stock for bracelets, anklets, girdles, and other articles of jewelry.

This application is a division of our application for Letters Patent of the United States filed November 23, 1933, Ser. No. 699,476.

The ornamental stock now in use include stock formed with prismatic depressions, preferably formed by stamping the stock with diamond dies, whereby the stock when made into jewelry reflects light brilliantly and presents the appearance of jewel inserts. This stock when used for bracelets, for example, has heretofore been made as single rings for use in groups of three or more, the separate rings being joined or secured together by means of a connecting band or the like.

We have devised a novel apparatus for producing the novel stock in the form of a continuous metal spiral, of any desired length; and we have devised a manufacturing arrangement to control the spacing of they spiral turns, whereby the turns may be close, or may be uniformly spaced apart to permit the insertion of an ornamental spiral of different material, such as for example catalin of different colors.

To this end, we have improved the apparatus for manufacturing ornamental spirals, so as to utilize soft metal wire, which is hardened and elongated by working, whereby a novel product consisting of a continuous ornamental metal spiral of predetermined size and spacing is automatically obtained.

With the above and other objects and advantageous features in View, our invention consists of a novel apparatus, and a resulting novel product, as more fully disclosed in the detailed description following in conjunction with the accompanying drawings, and as more specifically defined in the claims appended thereto.

In the drawings,

Fig. 2 is a side elevation, parts being broken away;

Fig. 3 is a detail View, showing the mechanism for regulating the depth of the impression on the metal wire; y

Fig. 5 is a top view thereof, the wire being broken away to show the anvil surface;

(fCl. 29-33) Fig. 6 is a bottom view thereof, illustrating the shape lof the plate guide; n

Fig.l 'lis-a side elevation of Fig. 4, disclosing the spacing adjustment; 1 Fig. 8 is a perspective view of the resultant spiral, showing the spacing between the spiral turns; and

Fig. 9 is a detail perspective view showing the impressed design.

Referring to the drawings, the novel apparatus is generally similar to` standardpunch or impressing mechanism, and includes a base 10 adapted to be mounted on a bench or thelike, a body 1l receiving an` anvil xturejand a head 12 containing the usual plunger operating mechanism, the head l2 housing a reciprocating plunger 13. A powerpulley 14, see Fig. 2, rotates the usual shaft l5 of the plunger operating mechanism, and a pulley 16 is keyed on the plunger shaft to impart rotative movement to a fixture pulley 17, as by a belt 18, whereby the fixture shaft 19 is rotated in timed relation to the reciprocating movement of the plunger.

The fitue shaft mounting The body 1l is provided with a horizontal longitudinal slot 20 in which `a fixture shaft holder 21 is slidably mounted, this holder being recessed at the rear and pivotally mounted on a transverse pivot 22 extending through an ear 23, integral with the body ll. The fixture shaft l9is housedv inthe holder, which acts as a bearing therefor. A cam lever 24, see Fig. 3, is swingingly mounted on the face of the body 1l, and has a cam nose 25 which engages the lower face of the holder, whereby adjustment of the arm 26 of the lever'by means of the spaced lock screws 2'7, 28 swings the holder to lift the fixture shaft V19 and thus regulate the depth of impress of the `reciprocating plunger on the metal wire, as hereinafter described. The belt 18 has suiiicient resilieiice tol compensate forslight changes in angularity of the fixture pulley 17.

The anvil fiati/.re y

The anvil fixture 29, see Fig. 2, is mounted on the body 11 in operative engagement with the forward end of the fixture shaft, and a guide shaft is positioned on the end of the fixture shaftV to receive the completed spiral as it leaves the anvil fixture.

Referring now to Figs. 1, 4, and 6, the anvil xture 29 has an anvil 31 rotatably mounted thereon and adapted to be keyed to the shaft 19, whereby the anvil is positively rotated. A gear 32, see Fig. 5, is secured to or formed integral with the anvil, and rotates an idler 33 for imparting positive motion to the gears 34, 35, secured toy or integral with a lower feed roll 36, and an upper feed roll 37 which is mounted in a swinging arm 38 and is resiliently pressed towards the lower feed roll by a spring 39, the spring being locked on an adjusting bolt 40 which is threaded in the fixture body and passes through a suitable bore 41 in the swingingarm. The lower feed roll is preferably knurled to provide a firm `grip on the wire, and may be roughened or embossed "to yfirmly grip the wire or tov roller determining'the spacing of the formed' coil. The forming roller 45 is rotatably mounted in an arm 47, see Figs. 4 and 7, which is detachably secured to the fixture body, and may be shifted vertically by removing `and resetting a pivot pin48, on which it may also be adjustably swung, see Fig. 7, in order to secure a predetermined uniform spacing between coils, as indicated in Fig. 8.

The operation of the mechanism The operation is best disclosed with reference to Figs. 4, 5, and l; the metal Wire W is received in the fixture between the two feed rolls, and is positively fed to the anvil, at which point it receives the rapid impacts of the rapidly reciprocating plunger. The wire W is of the variety known as dead soft in the trade, but becomes hardened by the working, as the plunger impacts on the anvil reduces its cross section and elongates its length to harden the wire. The worked wire is now led to the forming roller and the forming plate, which act as bending elements to curve the wire into a spiral of definite diameter and spacing, the diameter of the spiral being dependent onY the vertical adjustment of the forming roller and the coil spacing being dependent on the lateral adjustment thereof.

Although the stock may be with any desired design, the most suitable imprints are of diamond formation, and the preferred type is illustrated in Fig. 9, and is in the form of an inverted truncated pyramid having a rectangular base, a rectangular top, and sloping faces between the corresponding sides of the base and top.

It is thus evident that the invention comprises a novel process in that a dead soft metal wire is worked to obtain a desired impressing and to harden the wire, and is then bent into a spiral of predetermined diameter; a novel apparatus in that the mechanism is adjustable to gauge the impression and to set the spiral obtained for diameter and for spacing; and a novel product in that an ornamental spiral of desired width and spacing and of springy metal is obtained.

' While we have described a specific constructional embodiment of our invention, it is obvious that desired changes in the arrangement and the size of the parts and in their function and operation, may be made without departing from the spirit and the scope of the invention as defined in the appended claims.
